GTA: The Enchanted Cave 2

You heard that the cave holds a lot of treasure and you are a guy that is down to his last money. However, getting the treasure aren't easy at all since you need to fight hordes of monster. Anyway, that is the deal as you need to put your line in danger to make money.
The idea in this game is to explore the cave and get anything that you can grab your hands too. However, some of the treasures can't be taken outside of the cave. Of course, you would make money from killing monsters and selling some items you found lying in the cave.
